Referring to fig. 1 and 2, a first embodiment of the present invention provides a head-worn earmuff, which includes a shell 1, a single body 2 and an ear pad 3.

Specifically, shell 1 is the arc structure, monomer 2 sets up the interior concave part of shell 1, the outer convex part of shell 1 is used for being connected with the head roof beam, ear pad 3 is the loop configuration, with the edge connection of shell 1, monomer 2 with form back chamber 4 between the inner wall of shell 1, the regional antechamber 5 that forms that ear pad 3 encircleed, be equipped with expansion groove 11 on the shell 1, expansion groove 11 with back chamber 4 intercommunication, the internal surface of ear pad 5 is the evagination structure.

The utility model has the advantages of, set up expansion groove 11 to establish 3 internal surfaces of ear pad into evagination structure, do not make change by a wide margin to wearing the ear muff is whole, realized the expansion of rear chamber 4 promptly and reducing of antechamber 5, rear chamber 4 is favorable to the low frequency effect greatly, and antechamber 5 is little to the high frequency decay reduction, and the frequency response is wideer.

Preferably, the inner wall of the expansion slot 11 is provided with 3 grooves 12, and the size of the expansion slot 11 can be further increased by the grooves 12.

Specifically, the inner diameter of the ear pad 3 becomes gradually smaller in a direction away from the housing 1.

It should be noted that this structure increases the length from the outside of the ear pad 3 to the innermost portion thereof, that is, increases the depth of the front chamber 5, which is less likely to cause squeal.

Specifically, the edge of the shell 1 is provided with a snapping portion, and the shell 1 is connected with the ear pad 3 through the snapping portion 13.

In this embodiment, a rubber layer 31 is disposed at the connection between the ear pad 3 and the housing 1, and the rubber layer 31 is bonded to the ear pad 3.

It should be noted that the ear pad 3 can be made of sponge, the rubber layer 31 is made of rubber with high toughness, and can be stably clamped with the engaging portion 13 to a certain extent, and the ear pad 3 of the embodiment is not easy to fall off compared with the direct clamping of the ear pad 3 with the engaging portion 13.

In addition, the shell 1 is also provided with a sound output plate 6, the sound output plate 6 is in contact with the edge of the shell 1, the sound output plate 6 can be fixed on the shell 1 by adopting screws or glue, and the sound output plate 6 can also be clamped between the ear pad 3 and the shell 1 by utilizing the ear pad 3. The sound output plate 6 is provided with a plurality of sound output holes, and the sound output holes are used for transmitting sound.
